Hi there,
we use SNAP to post to FB, G+ and Twitter. We alwyas use a featured image sized 1200×627 and use the FB option “attach link to blog post” to achieve having Facebook post the large images.
This worked like a charm, until yesterday. In the morning I made a post, totally fine. In the afternoon, the next post appeared correctly (with the right image) on Twitter and G+, but on FB it used a totally different image from another post, not even the content itself.
I can’t figure out what the problem is. Nothing changed in configuration between morning and afternoon.
Can you please help me?!
